Radiation-Induced Chemistry of Carbon Dioxide: A Pathway to Close the Carbon Loop for a Circular Economy

Frontiers in Energy Research, 2020
Recent advances in modular nuclear reactors could facilitate the use of irradiation to produce fuels and chemicals using anthropogenic CO2. One of the challenges in CO2 conversion reactions is the stability or low reactivity of CO2.
